CUTTING IMAGHINE.

Application filed June 3,

T 0 all whom it may concern:

Be it known that I, EUGENE CoN'rr, a citchine of this type which is ofimproved construction and cuts the material in an improved and moresatisfactory manner. Inasmuch as my machine is of particular utility inthe manufacture ofpaper tubes I have chosen, for purpose ofillustration, a machine designed for cutting such tubes. In the drawingsaccompanying this specification and forming a part thereof:

Figure 1 is a side elevation of this illustrative embodiment of myinvention;

Figure 2 is an end elevation of the machine shown in Figure 1;

Figure is afplan of this machine; while Figure 4- represents a'detailview of certain portions of this machine;

Many of the tube forming machines in use. at the present time produce atube which is continuously fed from the machine in one continuous tubeof great length and must thereafter be severed into the desired shortsections. The machine which I have herein illustrated is provided forthis purpose and in operation may be secured to and made a part of thegeneral tube forming machine. I have omitted, however, all illustrationof any tube forming machine and have merely shown the tube 11 as it isbeing fed forward from the forming machine.

Mechanism is necessary to perform the cutting operation and thismechanism is herein shown as a rotary disc-cutter 12 secured to a shaft13 which carries a driving pulley M adapted to be driven by a belt (notshown) and is rotatably mounted on bearings 15 supported in standards 16which rise from a horizontalplate 17.

Means are provided to move this cutting mechanism into and out offunctioning position and this means is herein shown as an arm 18 whichis apertured at 19 to receive a pin 20 secured to the plate 17 and thusrotatably support the cutting mechanism and which is itself carried by ashaft 21 rotatably mounted in a pillar 22 which rises 1922. Serial No.565,646.

from a web 23 which in turn is supported by bearings 24 secured to thebase plate 25 of the machine frame 26. The shaft 21 and arm 18 arerotated by means of a bevel gear 27 secured to the lower end of theshaft 21 and driven by a cooperating gear 28 secured to the drive shaft29 which is rolatably mounted in the bearings 24. The pin 20 may be heldin positionin the arm 18 by means of .a nut 36.

In order to further govern the movement of the cutting mechanism and tohold the plane of the cutting disc 12 constantly perpendicula r to agiven fixed line, in this case the axis of the tube 11, means areprovided to govern the rotation of the pin 20 in the aperture 19 andthis means is herein shown as a parallel link mechanism consisting ofthe rods 30 and 31 secured at one end to the plate 17, a disc 32supported in any suitable manner and secured to the free ends of therods 30 and 31, and a second pair of rods 33 and 34 secured at one endto the disc 32 and at the other end to a fixed abut ment 35.

It will be understood from the above de scription that rotation of themain shaft 29 acts through the bevel gears 28 and 27 to rotate thevertical shaft 21'and thus cause the arm 18 and the cutting mechanismcarried thereby to rotate about the axis of the shaft 21 into and out offunctioning position while the parallel link mechanism causes thecutting mechanism to rotate in the arm 18 to hold the plane of thecutting knife continuously perpendicular to the axis of the tube 11.

- troduce a shearing element into thecutting operation means areprovided to guide and hold the tube at the cutting point during thecutting operation. This means is herein shown as a guide 37 secured to apreferably rectangular rod 38 which is reciprocally mounted in bearings39 and 40 which are supported by a web 11 rising from the machine frame26 and braced to the base plate 25 thereof by means of suitablebuttresses 42. The guide 37 and rod 38 are biased longitudinally by aspring 43 encircling the forward end of the rod 38 and pressing againstthe bearing 39 and the enlargement 4. of the rod 38 but such movement ofthe rod is normally restrained by the engagement of the roller 45carried by the rod 38 .might be governed entirely by the cam 51- but inorder to secure greater accuracy in the cooperation between the guide 38and the cutter 12 an arm 53 is'projected laterally from the rod 38 andcarries a roller 54ar ranged to engage the proximate surface 55- of theplate 17 when forward movement of the guide 37 is permitted by the cam51.

With such a construction the depression 52 of the cam 51 is made ampleto permit the:

required forward motion and the cooper ation between the roller 54 andthe edge 55 of the plate 17 is. depended upon to exactly govern thisforward motion.

The guide 37' may preferably be formed with a funnel shaped entranceportion 56 leading into a bore 57 of substantially the size of the tubeto be out. If desired, a second tube guide 58 may be provided to supportthe-tube beyond the cutting plane.

It will be understood from the above description that the cam 51 actingthrough the bell crank lever 47 normally maintains the rod 38 andguide37 in the rearward position against the tension of the spring 43 butthat when the cam roller 50- rides into the depression 52 the restraintof the rod 38 is terminated and the spring 43 acts tomove forward therod and the tube guide carried thereby. The coordination of the partsis,

however, such that the edge 55 of the plate 17 is now. moved intoposition ahead of the roller 54 carried by the arm 53 of the rod 38 sothat the forward movement of the rod islimited by the engagement of theroller 54 with the surface 55 and thereafter the rod moves forward atthe same speedas the plate 17 until the cuttingoperation is completedand the depression in the cam 51 has passed the roller 50 at which timethe cam 51 acts through the bell crank lever 47 to move the rod 38 andthe guide 37 back into retracted position.

The moving parts 'of this machine and th connections therebetween are soproportioned that the movement of the cutting mechanism about the axisof the shaft 21 moves the rotary cutting disc across the path of thetube to permit the disc to cut the tube; that the forward movement ofthe disc in its rotation about the axis of the shaft 21 at the time inwhich it is cutting the tube is substantially equal tothe rate of feedof-the tube; that the cam 37 hasat this time released the rod 38 so thatduring the cutting operation the roller. 54 is in engagement with thesurface 55 and the rod 38 and guide 37 are moving forward at the samespeed as the rotary cutting disc and the tube; and

that the guide 37 is in such position that the forward end thereof bearsagainst the rear "side of the cutting disc 12 to thus introduce rial,.apivoted arm having a point thereof.
